Hi All, In my work I need to store large amount of data into kernel space and also need to manipulate those data. Can I use Relay FS for it ? 1. Is there any limit on size of data to be stored per CPU Channel i.e Relay FS ? 2. How much does it effective compare to Scatter Gather list to perform operation on buffered data ? 3. Accessing this data from User Space Application . Any advantages ? Waiting for your response. Thanks.

I haven't used RelayFs, but AFAIK it was designed for transfering huge (dont know the exact limit) amounts of data from user space programs to kernel space and vice versa. It implements per cpu buffers which can be directly mmapped and used. -- Regards, Sandeep. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
